Computer doesnt shutdown, hangs and doesnt install programs

Computer doesnt shutdown, hangs and doesnt install programs
Hi,

Recently my computer has started to behave weirdly the first thing that happened was that the computer started to hang permanently and i had to switch it off using the reset button. then it started to give me blue screens with the following messages Stop:0x0000008E, C0x0000005, 0x8307B6F1, 0xAF40bb28, 0x00000000
along with this what has happened is that my computer doesnt shutdown it hangs on logging off. after all this i ran a spyware scan and then checked for registry errors cleaned everything but no luck
so i decided to reinstall windows as i entered the setup it gave me a message windows could not retrieve information about the disks on this computer i restarted virtual disk and nothing happened its the same also sometimes it gives me an error winsetup.dll is either corrupted or missing when im installing windows again.

P.s: my computer is not installing any softwares also the installer hangs and doesnt progress and when i double click a software it takes alot of time to open.

thank you...
